If this doesn't solve your problem, remove all the PCI or ISA components. then remove your IDE and floppy devices, and try again. If that still does not give you output on the serial port, you likely have a bad flash or bad cable (you did test it, right?). if you get partial output from the serial, but do not get to the point where you see your payload booting your system, then its time to upload the serial output you're getting after simplifying your hardware configuration to a paste website, and drop by IRC or the mailing list, and ask for help.

Build tutorial

First, before thinking of using coreboot, make sure you have a backup of your current BIOS image(see Flashrom), and the correct facilities to replace that image, if it becomes corrupt. Assuming you have a backup and restore procedure, continue with the following(which may destroy your board anyways! you have been warned!)

It is recommended that you have a known good PCI video card, a known good single sided PC100 non-ecc dimm, and a known good null modem cable before you proceed, for error recovery. At this point, it is recommended that you have many dimms, as the timings are compiled into the bios, and theres no good way to know your dimm is going to work after flashing.

CoreBoot has multiple Payloads used for the boot process (SeaBIOS, FILO, GRUB2, etc), and you must build a payload first, so that CoreBoot can build it into itsself.

after your payload is compiled(assuming you compiled the FILO payload), copy the resulting file to /tmp/filo.elf, then:

If in your output, you do not see the 'Enabling refresh' line, your ram chip is not being detected, or refreshed. try a different dimm, and make sure you're placing it in slot 1 (the slot closest to the CPU).

If this doesn't solve your problem, remove all the PCI or ISA components. then remove your IDE and floppy devices, and try again. If that still does not give you output on the serial port, you likely have a bad flash or bad cable (you did test it, right?). if you get partial output from the serial, but do not get to the point where you see your payload booting your system, then its time to upload the serial output you're getting after simplifying your hardware configuration to a paste website, and drop by IRC or the mailing list, and ask for help.
